 *  RGB Color to Prewitt Gradient Vector conversion using user selected fixed mask size and gradient distance method.
 *  Functions support up to 4 optional single channel output gradient vectors, X (vertical), Y (horizontal), magnitude, and angle
 *  with user selectable distance methods.  Output for a particular vector is disabled by supplying a NULL pointer for that
 *  vector. X and Y gradient vectors are in cartesian form in the destination data type.  
 *  Magnitude vectors are polar gradient form in the destination data type, angle is always in floating point polar gradient format.
 *  Only fixed mask sizes of 3x3 are supported.
 *  Only nppiNormL1 (sum) and nppiNormL2 (sqrt of sum of squares) distance methods are currently supported.
 *
 * Currently only the NPP_BORDER_REPLICATE border type operation is supported.  Borderless output can be accomplished by using a
 * larger source image than the destination and adjusting oSrcSize and oSrcOffset parameters accordingly.

 * For the C1R versions of the function the pDstMag output image value for L1 normalization consists of

 * the pDstY value and the pDstX value at that particular image pixel location.
 *
 * For the C3C1R versions of the function, regardless of the selected normalization method, 
 * the L2 normalization value is first determined for each or the pDstX and pDstY values for each source channel then the largest L2
 * normalization value (largest gradient) is used to select which of the 3 pDstX channel values are output to the pDstX image or 
 * pDstY channel values are output to the pDstY image.
 * For the C3C1R versions of the function the pDstMag output image value for L1 normalizaton consists of the same technique
 * used for the C1R version for each source image channel.  Then the largest L2 normalization value is again used to select which

 * For the C1R versions of the function the pDstMag output image value for L1 normalization consists of

 *  Performs Canny edge detection on a single channel 8-bit grayscale image and outputs a single channel 8-bit image consisting of 0x00 and 0xFF
 *  values with 0xFF representing edge pixels.  
 *
 *  The algorithm consists of three phases.  The first phase generates two output images consisting
 *  of a single channel 16-bit signed image containing magnitude values and a single channel 32-bit floating point image containing the angular
 *  direction of those magnitude values.   This phase is accomplished by calling the appropriate GradientVectorBorder filter function based on
 *  the filter type, filter mask size, and norm type requested.  The next phase uses those magnitude and direction images to suppress non-maximum
 *  magnitude values which are lower than the values of either of its two nearest neighbors in the same direction as the test magnitude pixel in 
 *  the 3x3 surrounding magnitude pixel neighborhood.  This phase outputs a new magnitude image with non-maximum pixel values suppressed.  Finally, in the
 *  third phase, the new magnitude image is passed through a hysteresis threshold filter that filters out any magnitude values that are not connected
 *  to another edge magnitude value.   In this phase, any magnitude value above the high threshold value is automatically accepted, any magnitude
 *  value below the low threshold value is automatically rejected.  For magnitude values that lie between the low and high threshold, values are
 *  only accepted if one of their two neighbors in the same direction in the 3x3 neighborhood around them lies above the low threshold value.  In other words,
 *  if they are connected to an active edge.   J. Canny recommends that the ratio of high to low threshold limit be in the range two or three to one, 
 *  based on predicted signal-to-noise ratios. The final output of the third phase consists of a single channel 8-bit unsigned image of 0x00 and 0xFF 
 *  values based on whether they are accepted or rejected during threshold testing.
 *    
 * Currently only the NPP_BORDER_REPLICATE border type operation is supported.  Borderless output can be accomplished by using a
 * larger source image than the destination and adjusting oSrcSize and oSrcOffset parameters accordingly.

 *  The second phase averages those products over a window of either 3x3 or 5x5 pixels around the center pixel then generates the Harris corner

/** @defgroup image_filter_histogram_of_oriented_gradients_border HistogramOfOrientedGradientsBorder
 * Performs Histogram Of Oriented Gradients operation on source image generating separate windows of Histogram Descriptors for each requested location.
 *
 * This function implements the simplest form of functionality described by N. Dalal and B. Triggs. Histograms of Oriented Gradients for Human Detection. INRIA, 2005.
 * It supports overlapped contrast normalized block histogram output with L2 normalization only, no threshold clipping, and no pre or post gaussian smoothing of input images or 
 * histogram output values. It supports both single channel grayscale source images and three channel color images.  For color images, the color channel with the
 * highest magnitude value is used as that pixel's magnitude. Output is row order only. 
 * Descriptors are output consecutively with no separation padding if multiple descriptor output is requested (one desriptor per source image location).
 * For example, common HOG parameters are 9 histogram bins per 8 by 8 pixel cell, 2 by 2 cells per block, 
 * with a descriptor window size of 64 horizontal by 128 vertical pixels yielding 7 by 15 overlapping blocks 
 * (1 cell overlap in both horizontal and vertical directions).  This results in 9 bins * 4 cells * 7 horizontal overlapping blocks * 15 vertical overlapping blocks or 3780 
 * 32-bit floating point output values (bins) per descriptor window. 
 * 
 * The number of horizontal overlapping block histogram bins per descriptor window width is determined by
 * (((oHOGConfig.detectionWindowSize.width / oHOGConfig.histogramBlockSize) * 2) - 1) * oHOGConfig.nHistogramBins. 
 * The number of vertical overlapping block histograms per descriptor window height is determined by 
 * (((oHOGConfig.detectionWindowSize.height / oHOGConfig.histogramBlockSize) * 2) - 1)
 * The offset of each descriptor window in the descriptors output buffer is therefore 
 * horizontal histogram bins per descriptor window width * vertical histograms per descriptor window height 32-bit floating point values 
 * relative to the previous descriptor window output.
 *
 * The algorithm uses a 1D centered derivative mask of [-1, 0, +1] when generating input magnitude and angle gradients. 
 * Magnitudes are added to the two nearest histogram bins of oriented gradients between 0 and 180 degrees using a weighted linear interpolation of each
 * magnitude value across the 2 nearest angular bin orientations. 2D overlapping blocks of histogram bins consisting of the bins from 2D arrangements of cells are
 * then contrast normalized using L2 normalization and output to the corresponding histogram descriptor window for that particular window
 * location in the window locations list.

 * 
 * Optionally the function can return connected region information for the filled region in the pConnectedRegion
 * NppiConnectedRegion structure in host memory. The oBoundingBox x and y will be set to the left and top coordinates and width
 * and height will be set to the right bottom coordinates of the bounding box relative to pSrcDst.  Set pConnectedRegion to NULL
